OPERATING THE MACHINE
1 Follow the instructions in the Preparing the Machine for Use section of this manual.
2 Press the Handle Release Pedal (16) to lower the handle into the operating position, or for 18FLX / 18ST push down on the Brush Pressure
Control Knob (17) to release the machine from the storage position.
3 Loosen the Handle Height Adjustment Knobs (21A) and adjust the handle height to the most comfortable position for the operator. Re-tighten the
knobs once the desired height is reached. Or lift up on Handle Position Adjustment Lever (21B) to adjust to a comfortable height.
4 Adjust the Nozzle Selector Knob (9) to either “maintenance” or “restoration” mode, if equipped with two spray nozzles (16XP, 18FLX, AX 410).
Maintenance Mode: Lower solution fl ow, recommended for frequent surface cleaning.
Restoration Mode: Higher solution fl ow, recommended for less frequent deep cleaning.
5 Plug the machine into a properly grounded outlet. To start the vacuum motor, solution pump and brush motor…
AquaClean machines: Turn Power and Extract / Accessory Switch (23) to the extract On (I) position (brush symbol).
AX 410: Select the extract position (brush symbol) on the Extract/Accessory Switch (25), then turn the Power Switch (26) to the On (I) position.
6 Adjust the brush pressure. Turn the Brush Pressure Control Knob (17) counter-clockwise to decrease the brush pressure and clockwise to
increase the brush pressure. The machine should assist, but not propel itself (on carpet) when the brush is properly adjusted.
7 Continually hold the Solution Switch (1) to dispense solution. Once the Solution Switch (1) is released the solution fl ow will stop. If equipped with
Solution Switch (Constant or Intermittent) (24), solution is dispensed in two ways.
• When the Solution Switch (24) on the panel is in the “constant” position, solution is dispensed continuously and the Solution Switch (1) is
disabled. This is mainly used when the machine is used in the high productivity walk behind mode.
• When the Solution Switch (24) on the panel is in the “intermittent” position, solution is dispensed only when the Solution Switch (1) is pressed.
8 Begin cleaning by pulling the machine along in a straight line and overlap each pass by 2 inches (5 cm). Release the Solution Switch (1) prior to
turns to ensure complete extraction of solution from carpet.
9 Watch the fl uid entering the Recovery Tank Dome Lid (4). If there is a large amount of suds in the recovery tank, add a defoamer chemical to the
recovery tank.
CAUTION!
Empty the recovery tank before the fl uid or foam enters the vacuum motor.
If there is little or no fl uid entering the recovery tank, check the Solution Drain Hose / Level Indicator (15), the solution tank may be empty. Refi ll
the solution tank with water and the proper ratio of cleaning chemical.
10 The recovery tank has an Automatic Float Shut-Off (14) to block the vacuum system when the recovery tank is full. You can tell when the fl oat
closes by the sudden change in the sound of the vacuum motor. When the fl oat closes, the recovery tank must be emptied. The machine can
continue to dispense solution, but will not pick up water with the fl oat closed.
11 When the operator wants to stop cleaning or the recovery tank is full, release the Solution Switch (1). Then turn the power switch Off (O) and
unplug the machine.
12 Push the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose
(12) from its rear storage hanger, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled
fl ow of waste water). Refi ll the solution tank and continue cleaning.
USING ATTACHMENTS
To use accessory tools, disconnect the recovery hose at the Recovery Hose Connection (18). Attach the accessory’s recovery hose to the machine’s
Recovery Hose (3). Attach the accessory’s solution hose to the machine’s Accessory Solution Hose (2A), or Accessory Solution Port (2B) on 16ST /
18ST. When using accessory tools place the Extract/Accessory Switch (23 or 25) in the accessory position (wand symbol).
See your Nilfi sk-Advance Distributor for accessories that may be used with the AquaClean

pulling on the Pin Release (7) and sliding
the Vacuum Shoe (8) off. Then disconnect
the Recovery Hose (B) from the vacuum
shoe and connect to the squeegee tool.
Attach the squeegee tool to the machine

the vacuum shoe, simply pull the pin
release and slide the squeegee tool into
place.
